# script to email files as attachments.
# ------------------------------------
# Additional documentation for this script, including a brief introdcution
# to MIME can be found at: http://home.clara.net/dwotton/unix/mail_files.htm
# Written: Dave Wotton, July 1998, (Cambridge UK)
# This script comes with no warranty or support. You are
# free to modify it as you wish, but please retain an
# acknowledgement of my original authorship.
# Usage: mail_files [-t] mailid [ -c mailid ] [ -s subject ] [ -f mailid ]
# [-n file_list] [-u file_list] [-b file_list] file_list
#
# -f : The mailid of the sender ( defaults to your userid )
# Only userids that have been defined as "trusted" in the sendmail
# config file can make use of the -f option. For non-trusted users
# any value specified by this parameter will be ignored by
# sendmail.
# -t : The mailid of the recipient. Mandatory, no default
# multiple mailids can be specified, separated by commas.
# -c : The mailid of any carbon-copy recipients. Optional.
# multiple mailids can be specified, separated by commas.
# -s : The subject string. Optional, default = "Not specified".
# Enclose in quotes.
# -n : no-encode: indicates a list of files which are NOT to be base64
# or uuencode encoded. Multiple files may be enclosed in double
# quotes. Usual wildcard notation can be used. This option is
# for completeness and can be omitted because the default action
# is not to encode the file-list.
# -b : base64 encoding: indicates a list of files which are to be
# base64 encoded. Multiple files may be enclosed in double quotes.
# Usual wildcard notation can be used.
# -u : uuencode encoding: indicates a list of files which are to be
# uuencode encoded. Multiple files may be enclosed in double
# quotes. Usual wildcard notation can be used.
# file_list : The list of files to send as attachments with no-encoding
# (same as -n option, but the file list does not need to be
# enclosed in quotes if more than one file specified).
# Usual wildcard notation can be used.
# The program will also prompt for text to be supplied on standard input
# as the main text of the message.
# eg.
# 1) mail_files Dave.Wotton -b file9.gif t*.htm < /dev/null
#
# email file9.gif as a base64 encoded attachment and the t*.htm
# files unencoded.
#
# 2) mail_files Dave.Wotton -s "my test" -b "file1.gif file2.gif" \
# < /dev/null
#
# email file1.gif and file2.gif as base64 encoded attachments.
# The script makes use of perl's MIME package to perform the base-64
# encoding/decoding.
# Note that files destined for Windows environments should have a name of
# the form aaaa.bbb where aaaa is up to 8 characters long, and bbb is a
# 3 character sufix. The suffix determines which program is used to
# display/process the data at the remote end.
# Simple text files can be emailed unencoded. Binary files, or text files
# with long lines ( ie > 1000 chars ) should use the base64 or uuencode
# encoding procedures. Base64 is preferred because it is more universally
# supported. In particular, most PC mail-clients can automatically decode
# base64 encoded attachments. Note that simple text files with short lines
# which are destined for PC environments should not be base64 encoded.
# This is because PCs use a different line-break character to Unix.
# If the text is base64 encoded, the line-breaks are not converted
# automatically and so the data arrives at the remote end without
# line-breaks.
# set up a 'usage' routine
